Problems solved by technology

The scale of farming crayfish in rice fields is expanding day by day, but due to the special biological characteristics of crayfish, it is easy to form inbreeding and breeding of crayfish in the same rice field, which continuously reduces the genetic quality of the population
The greenhouse output of Chinese soft-shelled turtle is increasing year by year, but the quality and quality are not good, and the market sales are weak

Embodiment 1

[0066] Six flat rectangular paddy fields with good ecological environment and no pollution sources in Quanjiao County, Anhui Province were selected, with an aspect ratio of 2:1, and each paddy field was about 20 mu.

[0067] (1) Construct rice, shrimp and soft-shelled turtle co-cultivation area, crayfish fry breeding area, and Chinese soft-shelled turtle temporary breeding area, and separate each area with mesh to realize the diversification of rice field functions

[0068] The space-time distribution combination of rice, shrimp and soft-shelled turtle co-cropping paddy fields, in different spaces at the same time, or in different time periods in the same space, realizes that the same paddy field can meet the different needs of the growth of rice, shrimp and soft-shelled turtles. In the area where rice, shrimp and soft-shelled turtles are co-cultivated, from March to June, crayfish farming is mainly used; from June to July, rice seedling planting and rice management are mainly ...

Embodiment 2

[0083] Six flat rectangular paddy fields with good ecological environment and no pollution sources were selected in Huoqiu area, Anhui Province, with an aspect ratio of 2:1, and each paddy field was about 25 mu.

[0084] (1) Construct rice, shrimp and soft-shelled turtle co-cultivation area, crayfish fry breeding area, and Chinese soft-shelled turtle temporary breeding area, and separate each area with mesh to realize the diversification of rice field functions

[0085] The space-time distribution combination of rice, shrimp and soft-shelled turtle co-cropping paddy fields, in different spaces at the same time, or in different time periods in the same space, realizes that the same paddy field can meet the different needs of the growth of rice, shrimp and soft-shelled turtles. In the area where rice, shrimp and soft-shelled turtles are co-cultivated, from March to June, crayfish farming is mainly used; from June to July, rice seedling planting and rice management are mainly used...

Embodiment 3

[0100] Six flat rectangular paddy fields with good ecological environment and no pollution sources were selected in Dingyuan, Anhui Province, with a length-to-width ratio of 2:1, and each paddy field was about 30 mu.

[0101] (1) Construct rice, shrimp and soft-shelled turtle co-cultivation area, crayfish fry breeding area, and Chinese soft-shelled turtle temporary breeding area, and separate each area with mesh to realize the diversification of rice field functions

[0102] The space-time distribution combination of rice, shrimp and soft-shelled turtle co-cropping paddy fields, in different spaces at the same time, or in different time periods in the same space, realizes that the same paddy field can meet the different needs of the growth of rice, shrimp and soft-shelled turtles.

Abstract

The invention provides a method for ecological breeding of rice shrimp and soft-shelled turtles in paddy fields and directional selection of crayfish. According to the opportunity of co-production at the same time and in the same space, the biological characteristics of Chinese soft-shelled turtles that like to eat crayfish are used to remove residual crayfish in the paddy field. , to prevent crayfish from mating and breeding in the same paddy field. On the other hand, re-select crayfish parents in different places to realize directional optimization breeding of crayfish. Specifically, it includes a crayfish directional breeding method, a rice shrimp and soft-shelled turtle ecological breeding method, a crayfish feed production method, a Chinese soft-shelled turtle feed production method, and a production method of Chinese soft-shelled turtle bait. The implementation of the method provided by the invention can improve the quality of crayfish and Chinese soft-shelled turtle, and the harvested high-quality rice can increase the output value per mu.

Description

technical field [0001] The invention relates to paddy field cultivation of crayfish and Chinese soft-shelled turtle, specifically including a method for directional breeding of crayfish, a method for ecological breeding of rice shrimp and soft-shelled turtle, a method for making crayfish feed, a method for making feed for Chinese soft-shelled turtle, and a method for making bait for soft-shelled soft-shelled turtle. field of farming technology. Background technique [0002] Crayfish belong to the phylum Arthropoda, Crustacea, Crawfishidae, and the genus Procambarus, also known as crayfish. It is loved by people and is the main species of shrimp farming at present. In recent years, due to the increase in market demand, the natural resources of crayfish have decreased sharply, and the price has gradually increased. The scale of farming crayfish in rice fields is expanding day by day, but due to the special biological characteristics of crayfish, it is easy to form inbreeding...
